Thermor Appliance Repair in Abbeydale

What does error code W.30.5 mean on a Thermor heat pump water heater?

Error W.30.5 indicates a mismatch between water heater settings and the ducting installed, or aeraulic pressure losses are too high. Check the ducting parameters in the installer menu and verify thermal exchange. If the fault clears when inlet ducting is removed, the ducting may need reconfiguration.

What does error code W.3 mean on a Thermor heat pump water heater?

Error W.3 indicates the water temperature probe is defective or reading outside acceptable parameters, typically showing an abnormal 85°C reading. Check all sensor connections and ensure proper positioning. Verify the ohmic value of the probe. If everything appears normal, the temperature sensor needs to be replaced by a qualified engineer.

What does error code W.52.8 mean on a Thermor Aeromax Split heat pump water heater?

Error W.52.8 indicates a PFC (Power Factor Correction) fault in the outdoor unit. This relates to electrical regulation in the external inverter unit. Contact a qualified engineer as the outdoor unit circuit board may need to be replaced.

What does error code W.9 mean on a Thermor heat pump water heater?

Error W.9 indicates the water temperature is excessively high, exceeding 80°C. This is a safety protection. Switch off the water heater and allow it to cool completely. Check if the supplemental electric heater is operating continuously. If the mechanical safety device has triggered, it may need to be reset by a qualified engineer.

What does error code W.52.7 mean on a Thermor Aeromax Split heat pump water heater?

Error W.52.7 indicates a general fault with the outdoor unit, typically caused by software incompatibility following a change of the interface card or outdoor unit card. A qualified engineer will need to replace or reprogram the affected cards to restore software compatibility.

What is the difference between inertia radiator heating body materials?

Aluminium heating bodies are highly reactive, ideal for irregular schedules with variable occupancy times. Cast iron bodies offer both inertia and reactivity, suitable for mixed routines. Heat transfer fluid bodies provide steady, sustained warmth best suited for regular schedules with consistent presence times.

Are Thermor water heaters protected against Legionella bacteria?

Yes, all Thermor electric water heaters include anti-legionella protection. The water temperature cannot be set below 50°C, which prevents bacterial growth. Legionella bacteria thrive between 23°C and 43°C, so maintaining temperatures above 50°C eliminates this risk.

How does the Boost function work on Thermor heat pump water heaters?

The Boost function provides hot water on demand by defining authorisation ranges for heat pump and electric element startup. Options include 24-hour operation or programmed time slots. This allows rapid water heating when you need extra hot water, even in economy mode.

Can multiple people in my household use the Cozytouch app?

Yes. Simply download the app on additional smartphones and sign in with the same username and password to access the same installation.

What is Frost Protection mode and when should I use it?

Frost Protection (also called HG or Hors Gel) maintains the room temperature at approximately 7°C to prevent freezing. Use this mode when you are away from your home for more than 48 hours during cold weather.
